we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...

Impact is one of very important subjects which always have been considered in mechanical science. Nature of impact is such that which makes its control a hard task. Therefore it is required to present the transfer of impact to other vulnerable part of a structure, when it is necessary, one of the best method of absorbing energy of impact, is by using Thin-walled tubes these tubes collapses unde...

impact is one of the most important subjects which always have been considered in mechanical science. nature of impact is such that which makes its control a hard task. therefore it is required to adopt a safe and secure mechanism for transferring the impact to other vulnerable parts of a structure, when it is necessary. one of the best methods of absorbing impact energy is using thin-walled tu...

energy is considered as an important input for agricultural products. a decrease in energy subsidy and its demand reduces agricultural outputs and raises the production costs. changes in production and costs may significantly affect welfare of the agricultural producers. the main objective of this study was to analyze the impact of increased energy prices (reduction in the subsidy) on the agric...

composites materials are widely used because of their high specific stiffness and strength. although the methods and techniques of designing these materials are well developed, however, the research on the behavior of these materials under impact and dynamic loadings are still under progress. in this article the crushing and energy absorption of composite tubes under axial dynamic loadings are ...

production subsidies, as a part of the strategy of economic growth of the agricultural sector, are of great importance around the world. subsidizing production inputs, particularly energy input, is another way of directing subsidy to the agricultural sector. in this research, production function of the agricultural sector was estimated using econometric methods and time series data. after calcu...

In recent years, Iran has increased energy prices somewhat, but because of the very low starting point they remain far below opportunity costs. In this paper we examine two broad issues: First, the estimated impact of the energy price (Gasoline and Jet Fuel) rises on producer prices entire the economy and transportation sub-sectors, and the second, the Estimated of gasoline and jet fuel elastic...

We present a complete calculation of the higher-order perturbative QCD corrections to inelastic photoproduction of J/ψ particles. A comprehensive analysis of total cross sections and differential distributions for the energy range of the fixed-target experiments and for inelastic J/ψ photoproduction at HERA is performed. The cross section and the J/ψ energy spectrum are compared with the availa...
